Daniel Gottlob Türk was a North German composer, performer, theorist and pedagogue whose Klavierschule remains a vital source for late 18th-century keyboard practice. Türk saw the keyboard sonata as the perfect medium for expressing the boldest and most experimental of ideas, and the Klaviersonaten Grössentheils für Kenner was his only collection dedicated to professional players. Symphonic novelties, exquisite polyphony and extreme contrasts of character and register are vividly brought to life on four historical keyboards from the Department of Musical Instruments at the Metropolitan Museum of Art, New York.
